Who it is for

eBay sellers and agencies sending Offers to Interested Buyers who want a margin-safe discount ceiling per listing before a human sends anything.

Delivery: usually a structured result, workbook, or ZIP depending on the tool.

How it stays safe

Friday calculates only from the list price, cost, fee, floor, quantity, and requested discount you supply. It reads no eBay account, API, listing, order, or buyer data and verifies no field. The final-value-fee percent is applied as a flat share of the sale price; real fees vary by category, store level, per-order fixed fees, promoted-listing rates, and surcharges, and contribution here omits returns, taxes, ad spend, and overhead. Friday does not publish listings and never sends an offer or message, predicts acceptance, or changes a price, listing, or promotion. Every price is a draft a human must verify against the live listing and current fees.
